ALFRED CARLSON, OF KLAMATH FALTISTCEEGON.

WIND-WHEEL ELECTRIC GENERATOR.

To all whom it may concern:

Be it known that I, ALFRED CARLsoN, citizen of the United States,residing at Klainath Falls, county of Kl-amath, State of Oregon, haveinvented certain new and useful Improvements in Wind-lVheel ElectricGenerators, of which the following is a specification, reference beinghad therein to the accompanying drawing.

This invention relates to a windwheel electric generator andparticularly to means for transmitting motion from the wind wheel to anelectrical generating apparatus.

The invention has for an object to provide a novel and improvedconstruction of electric generator driven from a windw'heel andelectrically connected to magnetically charge parts of the powertransmitting mechanism.

Other and further objects and advantages of the invention will behereinafter fully set forth and the novel features thereof defined bythe appended claims.

In the drawing :Figure 1 is a vertical section on line l1, Fig. 2; Fig.2 is a similar view at a right angle thereto; Fig. 3 is a verticalsection on line 33, Fig. 2; Fig. 4 is a detail section of the toothsocket of the transmitting wheel; Fig. 5 is a detail perspective of thetooth disposed in this socket, and Fig. 6 is a diagram of the toothhaving magnetic and nonmagnetic faces.

Like numerals refer to like parts in the several views of the drawing.

The numeral 10 designates the base of the wind wheel which may bemounted upon any desired tower or other structure and is formed with theprojection 11 which is emhead 13. These parts are mounted for freerotation by means of the ball bearings 14. The upper portion of the headis provided with bearings 15 for the shaft 16 of the wind wheel 57, andthis head has also secured thereto the tail or vane 18 by which it isretained in proper position relative to the direction of the wind.

The shaft 16 is provided with a transmitting wheel 17 secured theretoand formed with a series of sockets 18 upon one face thereof adapted toreceive the shanks 19 of the teeth 20 which are secured in the socketsby means of the cross pin 21 extending through the aperture 22 of theshank. These teeth are formed of magnetic material, but

have a face 23 of nonmagnetic material in l 1909. Serial No. 511,917.

order to facilitate their operation as hereinafter described. The wheel17 may be inclosed by any desired form of casing as shown at 24 and isadapted to mesh with a worm gear 25 disposed upon the shaft 26 which ismounted in bearings 27 upon the head 13. The worm wheel 25 is secured tothis shaft and is provided with ball bearings at one end to resist theend thrust due to the action of the transmitting wheel thereon.

At one end of the shaft 26 an armature wheel 30 is provided which hasthereon a winding 31 divided into sections and connected by conductors32 with the sections of a commutator 33, as shown in Fig. l. The casing34 surrounds this wheel and is provided with a series of field magnets35 connected in series with each other, as shown in Fig. l and also withthe armature brushes Patented Aug. 16, 1910.

36 by means of the lines 37, as shown in Fig. 1. The brushes 36 arecarried by the removable insulated plate 38 which is secured to thecover 39 of the casing 3-1 so as to inclose and protect the parts of thegen erator. This plate 38 is retained in position by means of the screws10 and carries posts 11 upon which the brushes 36 are mounted. Thecurrent generated is conducted from these posts by means of lines 12 inany desired manner, for instance, by means of an inclosing insulation 43extending downward through an aperture 1st through the depending tube 45carried by the head 13. In order to permit a rotative movement of thishead the wires are separated at the lower end of the head and providedwith contacts 46 which rest upon plates 47 from which conducting wires48 extend, as shown in Fig. 2. The casing cover 39 is provided withcontact springs 50 with which the conductor 37 from the field magnets isconnected. In order to permit the convenient removal of the plate 38 foraccess to the armature the posts of this plate have secured thereto aspring 51 which normally engages the spring 50 in order to securecircuit therethrough. The hub 52 of the transmitting wheel is insulatedfrom shaft 16 and provided with a magnetic winding 53 adapted to becharged through the line 54: by a shunt or other current arranged forthat purpose. It will therefore be seen that the invention embodies anovel and improved structure by which the power transmitted from a windwheel may be converted into electrical energy and this effected by meansof an ordinary windwheel with which the parts 6 i e tetlfiind which alsorotates the shaft /lfv which the driving function is performed.

The wind wheel shaft is provided with a transmitting wheel the teeth ofwhich are disposed to cooperate with the worm gear upon the shaft of thearmature whee]. These teeth are provided at the front with a nonmagneticface, while the rear face thereof is magnetized from the coil upon thehub of the transmitting wheel and thus attracts the walls of the groovesin the screw on the armature shaft so as to secure a positive drivingaction between the parts, while the nonmagnetic face of the toothprevents attraction of that face thereof and the consequent frictionalresistance which would result therefrom. The power transmitted to thearmature wheel greatly increases the relative rotation thereof to thatof the wind wheel and thus secures the generation of the desiredelectrical energy which may be used or stored as desired. The drivingconnections by which the power from the wind wheel shaft is transmittedto the armature shaft prevent and equalize any vibration of the windwheel or irregularity in its rotation as the speed of the armature shaftis greater than the wheel shaft and its momentum produces a continuousrotation thereof so long as driving power is applied thereto.

Having described my invention and set forth its merits, what I claim anddesire to secure by Letters Patent is 1. In an electric generator, arotatably mounted head, a driving shaft mounted therein and providedwith a driving gear,

a countershaft disposed at an angle to said driving shaft and providedwith a cooperating worm gear, an armature disk carried by one end ofsaid countershaft, and a casing secured to said head to inclose saiddisk and provided with a series of field magnets cooperating with saidarmature.

2. In an electric generator, a rotatably mounted head, a driving shaftmounted therein, a casing secured to said head and provided with aseries of field magnets therein, an armature disposed upon said shaft tocooperate with said field magnets, a cover plate for said casingprovided with an insulated portion, commutator brushes carried by saidportion, contact springs carried by said brushes, and cooperatingsprings insulated from the cover and connected in circuit with saidfield magnets.

33. In an electric generator, a rotatively mounted head, a driving shaftmounted therein and provided with a gear, a countershaft disposed at anangle to said driving shaft and provided with a cooperating worm gear, acasing secured to said head and provided with a series of field magnetstherein, an armature disposed upon said countershaft to cooperate withsaid field magnets, a cover )late for said casing provided with an insuated portion, commutator brushes carried by said portion, contactsprings carried by said brushes, and cooperating springs insulated fromthe cover and connected in circuit with said field magnets.

In testimony whereof I aflix my signature in presence of two witnesses.

ALFRED CARLSON.
